CHAIN-LINK.

Specification of Letters Patent.

Patented A11 5,1913.

Application filed April 29, 1913. Serial N6. 764,303.

To all whom it may concern:

Be it known that I, SAMUEL ROSENBERG, a subject of the Czar of Russia,residing at New York city, borough of the Bronx, county and State of NewYork, have invented certain new and useful Improve ments in Chain-Links,of which the following is a full, clear, and exact description.

My invention relates to improvements in chain links, more particularlyto that class of links used to form heavy metallic chains: employed forthe suspension of chandeliers or other fixtures, the object of myinvention being to provide what I term a duplex link, adapted for thepurpose mentioned, of comparatively large size, but light in weight, thecomplete link being formed of flat metal strips bent into suitablyshaped loops spaced apart and having bars or connecting pieces tomaintain the loops in spaced relationship. By forming the loopsaccording to my invention, I can obtain an ornate chain in endlessvariety of designs without casting and with a minimum amount of loss ofmetal in the process of manufacturing. Heretofore, so far as I am aware,these large suspension chains were usually formed of connected unitarysolid metallic links, or of stamped metal loops having the desiredcontour, but in the process of manufacturing the same, considerablemetal was lost, which enhanced the cost of manufacture, as these chains,for the purposes mentioned, are usually made of the more expensivemetals, such as brass, bronze, or the like.

I will now proceed to describe my invention in detail, reference beinghad to the accompanying drawing, forming part of this specification,wherein Figure 1 is a perspective view of a chain link constructed inaccordance with my invention; and Fig. 2 is a cross section thereof on aline a-a Fig. 1.

In the accompanying drawing 1 indicates an inner loop of suitableoutline or design, the said loop being form-ed of a fiat strip of metal,such as brass, bent into the desired outline or contour. Surrounding theloop 1 but spaced apart therefrom and having an outline or contourcorresponding substantially to the contour or outline of the loop 1,

is a loop 2, the loops 1 and 2 being maintained in spaced relationshipby connecting or spacing bars 3, the loop 2 also being formed out of astrip of flat metal. The spacing bars 3 are preferably located at eachend of the loops and at each side thereof, such bars being secured tothe loops in suitable manner, by soldering, brazing, or otherwise. Thenumber and location of such spacing bars is not necessarily material, as

I may change both the number and location thereof to suit requirements.

It will of course, be apparent that the particular design of duplex linkwhich I have shown in the drawing is simply an illustrative embodimentof my invention, and that my improved chain link may be made in a greatVariety of designs without departing from the nature and scope of myinvention.

Having now described my invention in detail, what I claim and desire tosecure by Letters Patent is:

1. A chain-link of the character described, comprising an inner loop andan outer loop spaced apart, said loops being of flat metal of suitablecontour, and spacing bars connecting the ends of the loops and the sidesthereof.

2. A chain-link of the character described, comprising a plurality ofloops spaced apart, said loops being of suitable contour, and aplurality of spacing-bars connecting and maintaining the loops in spacedrelationship.

Signed at New York city, N. Y., this 26th day of April, 1913.
